摘要:
A heat exchange system for use in lubricating systems for aircraft turbofan engine equipment in which a lubricant is provided under pressure to spaces bounded at least in part by surfaces moving relative to one another, the heat exchange system for providing air and lubricant heat exchanges to cool the lubricant at selectively variable rates in the engine fan airstreams. A heat exchanger core is provided in a controlled air flow duct system opening at its plural entrances to the engine fan airstreams and having its outlet end opening about at the end of the fan duct nozzle.

A solid cast block of water soluble detergent is dispensed by obtaining a solid detergent article of at least twenty liters cast onto a longitudinally extending structural core and placing the article within the spray chamber of a dispenser such that the article is supported on the structural core. The detergent article is then rotated upon the structural core while dissolving solvent is sprayed upon the rotating article. The resulting detergent solution is dispensed to an end use point.

A network advisory system that provides advisory information to a field service provider is disclosed. The network advisory system receives collected data from one or more destination facilities and analyzes the information to generate advisory information. The advisory information is used by the field service provider to provide a service at the destination facility. The field service provider may receive the advisory information while in transit to the destination facility or while located at a destination facility. The field service provider receives the advisory information through a network connection. The network connection may be either a wireless connection or a land-based connection.
摘要:
This invention relates to an apparatus and method for diluting a chemical concentrate. More particularly, dilution control is achieved by monitoring two flow meters, comparing the flow rate information, and adjusting the diluent flow to achieve a predetermined dilution of the chemical concentrate. An air push is preferably used to deliver the chemicals to the utilization points. Also a controller is used to prioritize requests from the utilization points in a hierarchal fashion.
摘要:
An apparatus and method for programming a detergent controller to vary the detergent concentration set-point according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting and set point into the controller. The microprocessor then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor to the controller. To achieve detergent concentration levels quickly without incurring overshoot, the controller senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point. Thus, the controller can change the response function if and when conditions change.
摘要:
Disclosed is an indicator (15, 35) for determining the level of contents in an opaque, plastic container (10). The container (11) is filled with a solid chemical (11), such as a detergent. A spray of warm or hot water (19) impinges upon the eroding surface (16) of the solid chemical (11) to produce a chemical solution. The container (10) is provided with a thermo-chromatic strip (15, 35) for detecting the level of solid chemical (11) within the plastic capsule (10). A method of dispensing a solid chemical (11) and a dispensing container (10) are also disclosed.
摘要:
A network advisory system that provides advisory information to a field service provider and/or a management system is disclosed. The network advisory system receives collected data from one or more destination facilities and analyzes the information to generate advisory information. If the advisory information is deemed time-critical, the information is automatically transmitted to a management system to alert the system that a time-critical situation is resident at a destination facility. The management system may determine one or more appropriate field service providers to address the time-critical situation. If the advisory information is not deemed time-critical, the information may be stored by the network advisory system until access by a requesting entity—either a management system or a field service provider.
摘要:
A multiple product dispensing system includes a plurality of use solution dispensers and a controller for selecting one of the dispensers according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser dispenses a controlled concentration of use solution using a diluent delivery apparatus that delivers a diluent to form a liquid concentrate from a solid chemical composition, and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system to dispense a use solution of carefully controlled concentration, and the controller will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator. Therefore, the likelihood of operator error occurring is greatly reduced by the automatic selection of the proper dispenser and the control over use solution concentration.
摘要:
An apparatus for diluting liquid concentrate materials to liquid use solutions. Liquid concentrates comprise common household cleaning and sanitizing materials such as window cleaners, hard surface cleaners, floor cleaners, sink cleaners, tile cleaners, drain cleaners and openers, glass cleaners, food preparation units, sanitizers, disinfectants, floor finishes and other similar institutional or industrial aqueous or aqueous-alcoholic cleaning solutions. The aspirator system is adapted to receive a container of liquid concentrate in a reservoir. The reservoir contains device to open the liquid concentrate. Additionally the reservoir contains device to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a receiver for the empty container. The receiver has filling device for the container that can deliver dilute use solution to the container. As should be apparent, the liquid concentrate container and the dilute use solution container are substantially identical.
